Essential hypertension (EHT) is the most prevalent chronic medical condition and a major risk factor for cardiovascular morbidity and mortality. EHT often progresses and combines with hyperuricemia (HU) in clinical cases, which increases organ damage in patients with EHT. CT-707 order We compared serum metabolites in EHT patients with EHT+HU patients and to find metabolic markers and related pathways in the progression of EHT to EHT+HU.

A longitudinal study was carried out in 35 patients (initially EHT and EHT+HU one year later). With 10 metabolites in EHT+HU identified as potential biomarkers, linoleic acid metabolism, sphingolipid metabolism, steroid hormone biosynthesis, starch and sucrose metabolism and purine metabolism interacted with EHT+HU.

Distinct changes in the metabolomics profile of sera were observed among healthy controls (HC), EHT and EHT+HU groups. Uric acid (UA), L-lactic acid, and quinolinic acid may play important roles in the progression from EHT to EHT+HU. They were mainly involved in pyruvate metabolism, purine metabolism and nicotinate and nicotinamide metabolism pathways.

The continuous elevation of L-lactic acid and quinolinic acid might be useful for understanding the mechanisms of pathogenesis in EHT+HU and provide prospects for preventing the development of EHT and HU.

To determine factors associated with parents who plan to vaccinate their children against influenza next year, especially those who did not vaccinate against influenza last year using a global survey.

A survey of caregivers accompanying their children aged 1-19years old in 17 pediatric emergency departments in 6 countries at the peak of the coronavirus disease 2019 (COVID-19) pandemic. Anonymous online survey included caregiver and child demographic information, vaccination history and future intentions, and concern about the child and caregiver having COVID-19 at the time of emergency department visit.

Of 2422 surveys, 1314 (54.2%) caregivers stated they plan to vaccinate their child against influenza next year, an increase of 15.8% from the previous year. Of 1459 caregivers who did not vaccinate their children last year, 418 (28.6%) plan to do so next year. Factors predicting willingness to change and vaccinate included child's up-to-date vaccination status (aOR 2.03, 95% CI 1.29-3.32, P=.003); caregivers' influenza vaccine history (aOR 3.26, 95% CI 2.41-4.40, P<.010), and level of concern their child had COVID-19 (aOR 1.09, 95% CI 1.01-1.17, P=.022).

Changes in risk perception due to COVID-19, and previous vaccination, may serve to influence decision-making among caregivers regarding influenza vaccination in the coming season. To promote influenza vaccination among children, public health programs can leverage this information.

Following interstitial administration, most therapeutics and molecules are cleared from tissues via the draining blood capillaries. Macromolecules and delivery systems >20 kDa in size or 10-100 nm in diameter are, however, transported from the interstitium via draining lymphatic vessels as they are too large to cross the blood capillary endothelium. Lymphatic uptake of small molecules can be promoted by two general approaches administration in association with synthetic macromolecular constructs, or through hitchhiking on endogenous cells or macromolecular carriers that are transported from tissues via the lymphatics. In this paper we review the latter approach where molecules are targeted to lymph by hitchhiking on endogenous albumin transport pathways after subcutaneous, intramuscular or intradermal injection. We describe the properties of the lymphatic system and albumin that are relevant to lymphatic targeting, the characteristics of drugs and delivery systems designed to hitchhike on albumin trafficking pathways and how to further optimise these properties, and finally the current applications and potential future directions for albumin-hitchhiking approaches to target the lymphatics.Oral delivery of biopharmaceuticals, as insulin, is hampered by rapid degradation and inefficient absorption in the gastrointestinal tract (GIT). To solve this, a new class of biodegradable poly(lactic-co-glycolic)-poly(ethylene glycol) (PLGA-PEG) mucodiffusive nanoparticles (NPs) was designed. Specifically, these were decorated with site-specific conjugated human albumin, engineered for improved pH dependent binding to the neonatal Fc receptor (FcRn), which naturally mediates transport of albumin across the intestinal epithelium. The designed NPs of monodisperse 150 nm in size were 10% loaded with insulin and their surface was successfully functionalized with human albumin. Importantly, the engineered albumin-functionalized NPs bound human FcRn favorably in a pH dependent manner and showed enhanced transport across polarized cell layers. When orally administered to human FcRn expressing mice induced with diabetes, a reduction of glycemia was measured as a function of receptor targeting, with up to around 40% reduction after 1 h post-delivery. Thus, biodegradable PLGA-PEG NPs decorated with human albumin for improved FcRn-dependent transport offer a novel attractive strategy for delivery of encapsulated biopharmaceuticals across intestinal barriers.Multifunctional nanosystems that can transport therapeutic and diagnostic agents into tumor sites and activate their respective functions via tumor-microenvironment recognition are highly desirable for clinical applications. We fabricated pH and redox dual-activatable self-assembled nanotheranostics (named as DA-SNs) via coordination-driven self-assembly of chlorin e6 (Ce6) disulfide-linked pH sensitive polymer ligand, poly (isobutylene-alt-maleic anhydride-graft-methoxy-poly (ethyleneglycol)-graft-imidazole-graft-Cystamine-Ce6) [PIMA-mPEG-API-SS-Ce6], and gadolinium ions (Gd3+). DA-SNs exhibited uniform particle size of ~48 nm, excellent stability, and inherent biosafety. Negatively charged DA-SNs could prolong blood circulation time (t1/2 = 2.91 h) and improve tumor accumulation. Moreover, DA-SNs could undergo surface charge switch from negative charge to positive one in a slightly acidic tumor extracellular environment (pH 6.8), thus enhancing cellular uptake. After entering tumor cells, fluorescence, photodynamic therapeutic activity, and T1MR contrast from DA-SNs could be activated within this intracellular environment with lowered pH and high level of GSH.
